Its GHS Time

Page Navigation

Today is the 30 April 2021 – its GHS time!

Well the time has finally arrived, from today New Zealand has adopted the GHS 7 hazardous substances classification system for classifying our hazardous substances.

As you will know if you attended our webinar last week there are a few things to be aware of:  

1.  Most of the old classifications correlate to the new ones (correlation chart    

2.  Some substances may no longer be hazardous is they were 6.1E (acute toxicity) or 6.3B (mild skin irritant)     

3.  Your aerosols may now be considered flammable when they were not before (there is now a 1% threshold rather than the previous 45% for flammable ingredients)     

4.  Over 5,000 substances have had their approvals revoked (as they are now covered by a Group Standard approval), and you may need to assign a group standard to these if you import or manufacture these 

5. There is a 4-year transition period for labels and SDS to be updated for substances with existing approvals    

6. Substances with new approvals (not including substances under a group standard) need to comply now    

The Hazardous Substances regulations are not changing, and will still refer to the pre-2021 HSNO classifications that we have known and loved for 20 years
